A disk is fastened tothe inside of the main levers, which furnish ti e arm of the brush, andthe extended bristles are pressed together in front of the curb, Illt'ki1g the brush stronger where the most of the 0 can-- ings accumulate, andthe disk is beveled above the curb, thus releasing the bristles to theirnatural position. The braces of the frame holding the disk, are extendedabove it to receive the cover over the brush, to prevcntthe escape ofdust, which covers the pocket of the elevator, and the entire elevatorif desired. As the brush whirls it createsa suction which takes up thefine dust that an ordinary brush will not r'emove. which is preventedfrom-being drawn into the center of the brush bya canvas between thebrush boards, thus accomplishing all that could be accomplished by avacuum cleaner. 6 is the frame of the brush, 7 the brush boards, 8 thepinion wheels, 9 the expanding bars, 10 the expanding wheel, 11 a lcking bar, and 12 the vacuum cover,

and pocket of the elevator, all extend bethe center of the brush, theteeth of which pass through the ends of the bristles of the brush andthe base of the teeth is a scraper; and these combined keep the brushclean and cause the dirt to fall into the pocket of the elevator. "Twospiral springs hold them in position when the brush is raised andlowered. Another brush in circular form is set in the upper end of thetube that cleans the brackets, and causes the cleanings to fall into thebody of the vehicle, and these combined keep the machine in workingcondition. 15 is the center shaft, 16 the sprockets, 17 the pocket, 18the channel, 19 the apron, 20 the combined comb and scraper. and 21 thebracket brush. 63 is the brackets, 64 the comb scraper blade, 65 theteeth, and 66 the springs. I

A e'uidc wheel is set in a clevis on the end of a cross bar on anextension of the frame, which may be held in operative position by anyappropriate means runs on the face of the curb, on a line with the endof the brush when in the gutter, which holdslthe hind and when not inuse it is folded back on loosely on a vertical shaft in front, which isbcnt so as to. play before an index scale,

An indicator wheel is hung the guide wheel, 23 the indicator andjt theindex, 68 theclevis, 50 the leveler, and 7 0 the cross bar. I

Two main levers, one on each side, of the machine, are held in position.by staple brackets, on them interlocking with others fastened to theframe, and they furnish the. arms of the brush, and carry short shafts.set in detachable boxes Whichcarry gears onone end and sprocket-s onthe'other, the

gears meshing into those on th hind wheel a of the vehicle, which drivet e brush on one side and the elevator on the other. Two of theseinterlocking brackets are bolted to the frameof the vehicle one on eachside of the hind wheels, and two others opposite to them are iiiiltedtdthe main levers, and those on the frame of the body slide throughthose on the levers, and are fitted closely.

so as to hold the gears on the short shafts on the levers directly overthe gears on the wheels, and also hold the revolving brush at auniformdistance fromthetraclr of-Ihc wheels and on a line with the curbguide wheels. These short shafts create a differ ential, and permit thespa .e under the body to be free from obstructions, and permitdistributing .and dumping the cleanings;

These main levers also operate the channel and apron, and rake and hoes.They are connected at the top by a bar, and rods from their lower endsreceive another bar, to the center of which a wire rope is attachedtolift the brush, and permit it to tilt endwise. to accommodate itself tothe slant of the pavement. This rope extends over rollers,

to a spiral spring with a chain through it to limit its expansion, andhas tackle blocks in it, and it extends to the front to adruni at thefront of the machine, operated by a ratchet and hand lever-l'and pawland foot lever; thus drawing thf main levers down at the front andlifting them in the rear,-

to supplement their leverage. These main levers are fulcrumed on a shaftthrough the machine, and have slotted boxes to permit'them to play inunisr n with the spiral spring in the lifting rope; and both regulatethe tension of the revolving brush.

When the load is dumped in piles, they are higher than the channel andpocket of the elevator, and to protect them levelers are provided,consisting of steel.plates on the cross barv of the extension of theframe, to permit drivin over the load when the cleanings are use for graing purposes, and

to save levelingby hand. 50 and 51-are the Chains from the lifting barof the brush j to the upper frame are used to sustain its weight, whenbeing driven to and from theplace where used, being 52.

An odometer 53, determines the miles traveled, from which tocompute theyardage cleaned.

A seat with springs is provided for the operator being 5%.

The space under the seat can be utilized for carrying tools, used inexpanding the brush and operating the machine.

The capacity of the body 55, is about seventy five cubic feet. and thedoor56 is used to inspect the load, and the door 57 to load the debrisgathered by the rake.

The brake 58, is operated by the lever 59 at the front. As the cleaningsare loosened before sweeping, the power required tooperate the rake. andhoes, sweeper and elevator combined, is less than that required by theordinary sweeper alone.'which also loosens them. and an ext-ra' horsemaking a three horse team. is sufficient for the largest size,

and but one horse or a motor cycle used as a tractor. for the size thatis used to clean alleys and collect manure, or a separate tractor may beused for the largest size.

The merits of this invention, and im proved method of efficientlyperforming the entire process, of cleaning any pavement, in anyconditic'n. with a. single machine, operated while cleaning by a singleoperator, with a single supplemental lever-.and that does uniform work,can be run at a uniform 'rateof .speed, by the use-of a uniform amountof power: cannot be understood except by contrasting its work with the.

been performed.

Ordinarily the street is first sprinkled, for the purpose offacilitating loosening the mamethods by which the work has heretoforeterials that adhere to the pavement, finaliry\ loosened bv the brush orscrubber, whichcreates mud, and forms windrows in the gutters, asdiagonal brushesor scrubbers are 'used, where the most of thecleamngshave accummulated. This requires a strong tension on the brush. orscrubber, which rapidly wears them out and requires a great amount ofpower; The water carries much of the loosened materials into the basinsof the;

Its novelty consists in assembling in their proper relations the severalparts, each performing its portion of the process of cleanstitutc asingle machine, constituting the' general, combination; and also ofsub-com hin'ations, someof which are mechanical, be

cause.,of their juxtaposition '.to each otherof several parts, andothers coiiperative coinbin'ations; because they contribute to per.-form particular portions of the process; and some. of; the parts areeither new, or improvemerits upon other similar features embraced indiiferent combinations. The channel and pocket of the elevator aremechanically combined with the other parts, contributing to place thecleanings where they'can be elevated; but the slotted boxes for thefulcrum of the main levers are cooperatively combined with the spring inthe brush lifting rope, set in the center of the lifting bar, allcontributing to adjust the brush to the slant and irregular surface ofthepavement, and the comb scraper and bracket brush together, keep themachine in working order, and the guide-wheel and indicator Wheelcombined, fix and determine the position of the machine with referenceto the curb; and the coiiperation of the main levers with all of theoperating machinery, made as one operator to operate with the singlesupplemental lever the entire machine, when it isin operation cleaning,and creates a material combinatlon;

Inconstructing the machine, care shouldbe taken to set all boxes on theoutside of the frame, where they can be conveniently oiled, and will befree from dust.

Particular attention is called to the relative positions of the guidewheel, hind wheels of the vehicle, and position of the bristles of thebrush dmthe-curb. Also to the narrow overlapFringj-Ifoes set diagonallyto permit the dirt to .iio'vv over and betweenthem and throwing. he outof the gutters and toward the center of the elevator.

I- am aware that parts more or less similar to some of the elements ofmy machine have been used on fother machines, but I am not aware thatany other machines have these parts arrangedin the same manner, or thatthey are of the samespecific construction.

I have described what I conceive to be the best-mode of constructing mymachine,

and. theseveral parts thereof; but I do not limit myself to theparticular form or mode of operation described. Obviously any equivalentdevice may be substituted for each of the various elements, and themachine may be made of any size, and be drawn by animalsor by amechanical tractor,
